/*** AliasRc1 - pass 1 ALIAS record processing
|
|
*
|
|
* Purpose:
|
|
* Read and decode ALIAS OMF record (Microsoft OMF extension).
|
|
* ALIAS record introduces pair of names - alias name and substitute
|
|
* name. Enter both names into linker symbol table.
|
|
*
|
|
* Input:
|
|
* No explicit value is passed. When this function is called the record
|
|
* type and lenght are already read, so we can start reading name pairs.
|
|
*
|
|
* Output:
|
|
* No explicit value is returned. Names are entered into symbol table.
|
|
*
|
|
* Exceptions:
|
|
* Warning - redefinition of ALIAS <name>; substitute name changed
|
|
* from <name1> to <name2>.
|
|
*
|
|
* Notes:
|
|
* None.
